IMPROVEMENT IN MACHINES FOR MAKING HORSESHOES.

Specification forming part of Letters Patent No. 206,726, dated August6, 1. 7s;

application filed May 29, 1875'.

To all whom it may concern:

Be it known that I, DAVID II. HATLEE, of Clifton Park, in the county ofSara-toga and State of New York, have invented a new and ImprovedHorseshoe Machine, of which the following is a specification Figure 1 isa plan view of my improved machine. Fig. 2 is a detail view of theshoeclamping dogs. Fig. 3 is a detail view of one of the dies aroundwhich the shoe is formed. Fig. at is an inverted plan view. Fig. 5 is avertical section taken on line w xin Fig. 1. Fig. 6 is a transversesection taken on line 3 y in Fig. 1. Fig. 7 is a detail sectional viewtaken on line .2 e in Fig. 1.

Similar letters of reference indicate corresponding parts.

My improved machine for manufacturing horseshoes has a horizontal bed,of which a portion is movable and carries dies, around which the shoe isformed (from a bar of suitable length) by means of devices attached tothe fixed portion of the bed or frame of the machine, all of saiddevices being connected with and operated by the movable part of thebed, as hereinafter described.

In the drawing, A is the bed of the machine, which is supported 011standards B, and is slotted through the center throughout its entirelength and provided with tongues for guiding the movable bed 0, which isshorter than the stationary bed A.

In the upper part of the standard B a shaft, D, is journaled, whichprojects beyond the standards at each side of the machine. Upon one endof the shaft D is placed a fly-wheel, E, and upon the other end there isa crank, F, that is connected by the connecting-rod G with an arm, H,that is secured to the end of a rock-shaft, I, that is journaled in thelower part of the standards B. Said rock-shaft carries a toothed sector,J, that engages a rack, K, on the under side of the movable bed 0, andgives to the said movable bed a longi-' tudinal reciprocating motion.

The bed 0 carries two dies, L M, around which the shoes are formed. Thedie L has a projection, a, which engages the middle portion of the barfrom which the shoe is formed, and enters a recess in cap N when thelatter is brought down. The bar from which the shoe-blank is formed isbent around the die L while cap N is held down, and the ends of theshoe-blank are upset and thickened vertically by lateral pressureapplied by swinging benders or formers, as hereinafter described.

The cap N has an arm, I), which is pivoted in the end of the movablebed, and is curved downward and provided with a shoe, 0, that engages across-bar, d, which is secured to the stationary bed A, so as to closethe cap down upon the die at the proper instant and holdit in thatposition until the shoe-blank is bent and upset.

At the side of the stationary bed there are shears 0, having thestationary blade 0 and the movable bladef, which is secured to the leverP, pivoted in ears g that project from the bed A.

The longer arm of lever P extends forward, and is engaged by a cam, Q,on the shaft 1) once during each revolution of the said shaft, and tothe shorter arm of the said lever is attached a rod, 7:, that isconnected with a spring, i, that is suflicientl y strong to raise theupper shear-blade when the lever is not engaged by the cam Q.

A bar, R, which is secured to the bed A at right angles to the movablebed 0 and shearlever P, has at its inner and outer ends a pair of ears,j, between which a dog, It, is pivoted, and upon the bar R, between thedogs is, a slide, S, is placed, which is also provided with ears j andwith a dog, k.

The slide S is moved by a lever, T, which is pivoted to a bracketprojecting from one of the standards B, and is moved by mechanismpresently to be described.

The bar from which the shoes are formed passes between the ears j on thebar and 011 the slide and under the dogs is, and is moved forwardthrough the shears and across the movable bed 0 by the slide S. The endof the bar is received in a groove in the vertical face of the gage U.The face of the said gage is cut away near the bed A to admit of theforward movement of the bar after it is dropped by the shears.

In the bed A four similar vertical shafts, m, are journaled. Theseshafts are arranged in pairs, the shafts of each pair being on oppositesides of the movable bed (l, and the pairs of shafts are placed apart adistance equal to the distance between the dies L M.

Under the movable bed 0, and on opposite sides of the rack K, there areprojections or teeth a, which engage the notches 0 in the inner ends ofthe levers V V, which are secured to the lower ends of the shafts m. Inthe outer ends of the levers V V there are notches p to receive the nibsof the locking-levers \V W, which levers are pivoted to the bottom ofthe bed A. The plane ends of these levers in each pair adjoin each otherand are moved outward by followers A, that slide in grooves in the bedA.

The followers A have their inner ends beveled from each side toward themiddle, and are received by notches r in the sides of the movable bed 0when the levers \V W do not lock the levers V V, but are forced outwardso as to lock the said levers V Y twice during the stroke of the movablebed (3 by the projecting portions g at the sides of the notches r.

The arrangement of the respective pairs of locking-levers is such thatthe nibs of the first pair, "W, leave the notches in the levers V as thenibs of levers \V leave the notches in levers V, as shown in Fig. 4.\Yhile the followers A are forced outward the levers \V W temporarilylock the levers Y Y, so that the two formers s are caused to act in thedesired manner and succession.

The upper ends of the shafts we carry formers s, which carry the ironaround the dies L M as the shafts m are oscillated. The formers 8 eachhave a curved surface that corresponds nearly to the form of theexterior of one-half of the shoe. To one of the shafts m, near the gage1', is attached an arm, t, that is connected by a rod, '11, with thefeed-operating arm T. Between the pairs of shafts m upon opposite sidesof the movable bed there are holders 1 which receive the shoe-blank fromthe die L, and are provided with springdogs 2, which retain the blankuntil it is engaged by the projecting portion of the die M.

Near the. discharge end C of the machine there are holders B similar tothe holders B, which are provided with spring-dogs, which retain thefinished shoe until another is brought forward to take its place.

Upon the center of the shaft D is placed a heavy arm, D, having in itsouter end sockets a and clamping screws 1) for holding the creasing-diesc, which form the creases in the bottom of the shoe.

The operation of my improved machine is as follows: The bar from whichthe shoes are to be made being already heated is placed between the earsj and under the dogs k, and

even with the blade of the shears 0. As the machine is operated byconnection with any I suitable motor the bar is moved forward until ittouches the gage U, when the shears cut it, and it is received betweenthe cap N and movable bed 0 and carried forward between the formers s,which, being turned in the manner already described, bend the bar aroundthe die L, and at the same time upset or thicken it at the heel. Theforward movement of the bed 0 carries the shoe to the holders B, whosebeveled edges raise it from the bed C. The shoe is carried to the middleof the holder by the projection a on the die L, when the bed returns andthe operation just described is repeated. As the bed 0 makes aretrograde movement the die M is brought under the shoe contained by theholders B, and the projection u of said die engages the inside of thetoe of the shoe, and when the bed C again moves forward it carries theshoe under the guides d attached to the holders B and under the creasersc. The arm I) delivers the shoe finished to the holders B, where itremains until it is discharged by the entrance of another shoe in theholders. When the cap N makes its return movement it is closed down uponthe die L by an arm, 0, that is secured to the bed A and extends overthe top of the movable bed 0 nearly to the holders B.

In order that the shoe, when held by holders B, may rise sufficiently toallow the die M to pass under it, as above stated, Iconstruct thegrooves in said holder of considerably greater width vertically than thethickness ofthe shoe.

llavin g thus described my invention, I claim as new and desire tosecure by Letters latcut- 1. The combination of the cap N, having thedownwardly-curved arm I) and die L, with the horizontally-movable bed (land the fixed cross-bar n of the bed A and the formers s, whereby as themovable bed advances the cap is brought down and held on the die bycontact of said arm with the cross-bar, as shown and described.

2. The combination, in a horseshoe-machine, of the gage 1', having thegrooved face and cut-away side, with the shears O and headers or formerss, substantially as herein shown and described.

3. The combination of the bed t, having the teeth 12 and notches r,notched levers Y Y, locking-levers \V W, followers A, and the formers s,as herein shown and described.

4. The combination of the movable bed 0, dies L M, formers s, holders BB, and arm D, carrying the creasing-dies c, substantially as shown anddescribed.
